j My 4 invention relates to presses ing OrcOmpacting articlesormaterials, and, has been devised bundles of scrap iron or the like,:previously i5 heated-in a suitable: furnace. The compressing of-the hotbundles `will reduce their di.-y

4'mansions and thus facilitate `their further handling, andz'will also,if the-bundles are hot enough, cause theindividual pieces of scrap ironto become'welded to eachother,

thus producing bundles of great strength VvwhichA will not fall" apart`vvhen subjected subsequently to hammeiing,rol1ing,`and lilreoperations. The object of my invention is V` to produce a press of the'aboveindicated type which Will be operated readily and which, inparticular, Will includermovable ,parts torfacilitate the release ofthecompressed bundles from theV press and toy pre-- vent .theirstickingthereto.

Finally thelower surface of the member Gwill come incontactfwith the upper surface of the `bundle O, Which willthe-n be compressed during ther Jfurther downward movement ot thepressure member G. During such compression, thebundle will be coniineden tour sides, viz at the top by the pressure member G,

at the bottom by the top D of the die, and at the two longitudinal sidesby the parts H, J respectively. At the ends, however, the bundle O isunconiined, so that it can expand or lengthen out Jtreely While itscross section is being reduced `by compression. The .Operation havingbeen completed, the pressure member G moves up- Wardl to releasethe-bundle, the lowermost position of the prongs L beine indicatedV bydotted lines in Fig. A

During compression, the material .of the bundle U is forced into thecracks or joints between the die top D and the side members H, J, andalso to` a smaller extent, into the joint at the hinge l.' The materialenten readily thanV if ing these giointsavill tend to interfere withthe-.tree movement ot said parts and VWith thelrelease ot the bundlefrom said parts. To overcome these diiculties, l have provided tlieViiollmving features: First, the top vD projects beyond the head C.- andis'ot jsmall thickness, so that there is onlya Vnarrow `zone along whichthe die and the parts H, J may sticl `to each other owing to materialthat lhas found its Way between them. .'lherdieavill thusbe releasedinuchfin'ore the head C were flush With the top D. Second, the hingingot the side away from the member H, so as to release the compressedbundle O. This release may be obtained, evenin'the loiveii'nost positionof the pressure member, by moving the abutment M away from the` die.Generally,hoivever, it

,will be preterred not to disturb the adjustment of the abutment M.-,The third feature facilitating the release ofthe compressed Vbundle Aisthe slidingconnection between the die and the die-holder B. Thus, as thepres- -surenieniber -G' rises, it will not` have to '.,overco'me theVfractional resistance bet-Ween the members all, J and the edges oi `thedie Y top D, because if any material makes it stick '30 Y ,the abutmentM, the slight expansion of the i r die to drop back, at rM5' to saidparts H,TJ, the entire die Will rise with the pressure member G, andwhen lthe side member` J at the end of such rise clears compressedbundle@ Will swing the side member J on its hinge and thus allow the thesame time releasing the bundle 0. in order to prevent thehinge sure, lmayY give the member .Grr a non-hori- Zontal lower surface, for instancea plane inclined pressure surface, as at G in Fig. 3, or a wedge shapedpressure surface, as at G2 in Figs. l .and 5, and similarly the die topD may have a non-horizontal upper surface, for instance -theWedge-shaped or rootshaped surface D shown inv Fig. 5.
